Penetration blasting warhead containing active fragment inclusions in titanium alloy matrix and its preparation method

Abstract

The invention provides a penetrating blasting warhead containing active fragments in a titanium alloy matrix and a preparation method thereof. A partition is arranged between the warhead and the shell; a front-stage charge is installed in the warhead; a rear-stage charge is installed in the shell; Including titanium alloy matrix and active fragments, the titanium alloy matrix includes titanium alloy thin-walled cylindrical skeleton and titanium alloy metal powder, the wall of the titanium alloy thin-walled cylindrical skeleton is provided with an array of empty slots, and the active fragments are stuck in the array empty slots; titanium alloy thin-walled cylinder Skeleton, active fragments and titanium alloy metal powder are pressed into the shell; the front end of the shell is provided with an internal thread to connect with the external thread of the tail of the warhead; the tail end of the shell is respectively threaded with the body socket and the end cover, and the body socket is filled with a fuze. The present invention uses 3D printed thin-walled skeleton to fill and fix active fragments, which provides convenience for design and manufacture, and the skeleton material is the same as the shell base material of powder metallurgy, the inside of the shell has good compatibility, and the structural strength of the shell is improved. ensure.

Description

technical field [0001] The invention belongs to the field of fragment warheads, and in particular relates to a penetrating blast warhead whose titanium alloy matrix contains active fragment inclusions and a preparation method. Background technique [0002] Active structural materials are a new class of multifunctional materials that have emerged in recent years to meet the needs of national defense engineering. Foreign countries generally call this material ReactiveMaterials (reactive materials), also known as Impact-initiatedEnergeticMaterials (impact-initiated energetic materials), (hereinafter Collectively referred to as active materials), the fragments prepared by using active materials (hereinafter collectively referred to as active fragments) can not only have enough kinetic energy to penetrate the target but also produce additional chemical reactions and release energy to generate greater damage to the target during the penetration process of the target. Damage effect...
